To all whom it may concern:

Be it known that T, CHARLES B. TAYIDR, a citizen of the United States, residing at Winona Lake, in the county of Kosciusko and State of Indiana, have invented certain new and useful Improvements in Corner Feenforcements for Cartons; and I do de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use the same.

This invention relates to reenforcements forcartons, and especially to an improved internal reenforcement for the corners of cartons.

One object of this invention is to generally improve upon devices of this character by providing an improved reinforcing unit which is insertible within an ordinary carton having one or more floors or horizontal partitions and having two sets of intersecting partitions on each fioor, such as used for containing and carrying a number of glass jars, bottles or other fragile objects; also to obviate the necessity of changing the outward appearance of the carton, or of changing its construction further than to truncate the corners of the horizontal partitions.

A further object of this invention is to provide an improved reinforced carton in which a horizontal partition co-acts with the uprights on corner posts to reinforce the upright corners of the carton.

Other objects and advantages will be pointed out or implied in the following details of description in connection with the accompanying drawings in which Fig. 1 is a perspective view of my complete device with its cover open.

Fig. 2 is a vertical sectional view taken substantially along the line 22 of Fig. 1.

Fig. 3 is a horizontal detail sectional view, substantially along the line 33 of Fig. 2.

Fig. l is a perspective view of one of the unitary reinforcing devices, a portion being broken out of the middle thereof.

Fig. 5 is a perspective view illustrating four of the unitary reinforcing devices or posts set up in quadrangular relation and connected by wires at their bottoms and tops, to more clearly disclose the relation of these devices to one another when they are enclosed in the box.- or casing which is omitted in this figure.

Fig. 6 is a plan view of a floor or horizontal partition, one or more of which may be employed in connection with the structure disclosed in Figs. 1 and 5, according to the number of tiers of jars, cans, bottles or other articles to be contained in the casing.

Flg. 7 is a perspective View illustrating one. form of connection for the wires or cross braces which connects the corner posts or unitary reinforcing devices.

Referring to these drawings in detail, in which similar reference characters correspond with similar parts throughout the several views, and in which the carton proper is of ordinary construction, the invention consists in the construction and arrangement of parts which will now be described as follows This form of carton comprises a box which is generally indicated at 1, having a cover which is formed by two pairs of flaps 2 and 3. The box also comprises a bottom 4. This box is formed of fiber board or the like, and the flaps 2 and 3 are hinged on the walls of the box in the ordinary manner. The ordinary filler of this box comprises a lower cell-structure 5, a horizontal partition 6 seated on this lower cell structure, and an upper cell structure 7 seated on the partition 6. As illustrated in Fig. 1, the cell-structures comprise intersecting vertical walls which combine to form a lurality of substantially rectangular cels of equal capacity, the capacity varying according to the size of the glass jar or other article to be contained therein.

In order to accommodate the reinforcing devices of my invention, the corners of the horizontal partitions 6 are truncated as indicated at 6 in Fig. 3, and this provides angular spaces 7 at the respective upright corners of the box. Posts or upright bars 8 are seated in these upright corners of the box and extend through the spaces 7*, and the truncated corners of the partition 6 abut against the posts or bars 8 and secure them in their respective upright positions in said upright corners. The ends of each post are disposed in planes at right angles to the length of the respective posts, and two plane sides of each post are at right angles to each other as shown in Fi s. 2 and 3 and these two sides and ends of each post provide three sided corners at each of these ends. Upper and lower reinforcing plates not that is, the upper and lower ends of the upright corners of the box. Each of these plates is preferably quadran lar or rectangular in formation, and eac is provided with a pair of marginal flanges 9 which meet one another at right angles at 9*. These flanges are disposed at right angles to the main body of the plates 9 and therefore, a three-sided corner-space is provided for each plate 9, and this corner-space constitutes a seat in which one end of one of the bars 8 fits snugly. Although any appropriate means may be employed for securing the plates 9 to the respective bars or posts 8, I have here indicated one means as consisting of screws, nails or rivets 10 which extend through apertures of the flanges 9. When screws or nails are employed as such fastening means, thebars or posts 8 are preferably of wood, being of solid triangular formation in cross-section, but .the invention is not limited to this exact construction and material. When the members 9 and 8 are thus united, they form a unitary rigid structure such as shown separately in Fig. 4. When the bars 8 are formed of relatively tough and light wood, they are very efficient as means for reinforcing the upright corners of the box, and their efficiency is increased by the cooperation of the horizontal partition 6 whiohabuts thereagainst. Each reinforcing plate 9 is preferably provided with an aperture 11 adjacent to its inner corner, and strong cords or wires 12 extend through these apertures 11 in the manner illustrated in Fig. 1. The advantages of these struts in bracing the box or carton against diagonal strains is believed to be obvious without explanation.

In packing and assembling the elements of this carton, the 4 corner reenforcements 8 are first placed in the box 1, the lower cell structure 5 is then placed in the box, and the four corner jars "are placed to hold the corner reinforcing pieces in place, then finish the first layer of jars or other contents in the ordinary manner. The horizontal partition or center board is then placed upon this lower cell structure, which now holds the corner reinforcing pieces in place and now it will be easy to place the jars in the next cell structure. If you wish to make carton to hold more than two layers make the corner reinforcing pieces long enough to extend from bottom to top of box and put in more horizontal partitions and more cell structures.

en the packing of the carton has progressed to the stage shown in. Fig. 1, the cover-flaps 2 and 3 are folded inward over and upon the plates 9 and struts 12, and these flaps are then glued or otherwise secured to one another, or else, the box can be wrapped and tied for securing the cover flaps in closed position.

Referring now to Fig. 5 of the drawings, it will be seen that the wires 12 have their middle portions drawn toward each other and connected together by a wrapping of wire or string, or by any appropriate means, as indicated at 12. By removing the said means 12 each wire can be swung about its connections or ends 12 so that its middle portion extends outward and leaves a clear space between the upper ends of the corner posts or reinforcing strips for permitting the jars or other contents to be placedbetween these corner osts without interference. Referring to ig. 7, it will be seen that one of the wires 12 may be formed with a loop 12 and the other wire is formed with a book 12.

The floors or partitions illustrated in Fig. 6 can be made of any appropriate material, wood-fiber, wood or the like being preferable, and the truncated corners of the board serve as abutments .to bear against the intermediate portions of the corner posts and hold them in place.

It is notintended to limit this invention to the exact details of construct-ion as described but changes may be made within the scope of the inventive ideas as implied and claimed.

What I claim as my invention is:

A carton comprising a receptacle, superposed frames in said receptacle providing article receiving cells, a partition strip between said frames, and a reenforcement for said "frames within said receptacle, said reenforcement comprising corner posts fitting within the corner portions of said receptacle and engaging the corner portions of said frames, upper and lower plates fitting upon the ends of said corner posts and extending diagonally toward each other across the frames and having side flanges secured to the side faces of said posts, and trusses each being connected with the plates of corner posts atone side of the carton, the trusses being drawn inwardly and having their intermediate portions releasably connected.

In testimony whereof I have hereunto set I my hand.

CHARLES B. TAYLOR.
